Abstract

THE INVENTION RELATES TO A DRAG HEAD (1) OF A TRAILING SUCTION HOPPER DREDGER, COMPRISING A VISOR (2) WHICH IS DRAGGED OVER THE BOTTOM IN A DRAGGING DIRECTION AND HEREIN LOOSENS SOIL, AND A SUCTION CONDUIT (3) WHICH CONNECTS TO THE VISOR (2) AND WHICH DISCHARGES THE LOOSENED SOIL. THE DRAG HEAD IS PROVIDED WITH CUTTING BODIES FOR LOOSENING THE SOIL, WITH THE PROVISO THAT THE CUTTING BODIES COMPRISE BITS (20). HARDER SOIL CAN ALSO BE DREDGED WITH THE DRAG HEAD BY APPLYING BITS (20). THE INVENTION ALSO RELATES TO A METHOD FOR DREDGING AT LEAST PARTIALLY HARD BOTTOMS UNDER WATER WITH A TRAILING SUCTION HOPPER DREDGER EQUIPPED WITH THE DRAG HEAD. THE MOST ILLUSTRATIVE DRAWING IS
